Question

A student performs an experiment by ringing a bell in the air and in a pool and measuring the time it takes for a friend to hear the bell. In one or two sentences, make and justify a hypothesis on which medium the friend would hear the bell the fastest.(2 points)

Answer 1

Hypothesis: The friend will hear the bell fastest in the pool (through water) because sound travels faster in liquids than in gases — water transmits pressure waves much more quickly (≈1480 m/s) than air (≈343 m/s) due to its higher bulk modulus and closer particle spacing.
